title: "Announcing Rust 1.77.0" | ||
author: The Rust Release Team | ||
release: true | ||
--- | ||
|
||
The Rust team is happy to announce a new version of Rust, 1.77.0. Rust is a programming language empowering everyone to build reliable and efficient software. | ||
|
||
If you have a previous version of Rust installed via rustup, you can get 1.77.0 with: | ||
|
||
```console | ||
$ rustup update stable | ||
``` | ||
|
||
If you don't have it already, you can [get `rustup`](https://www.rust-lang.org/install.html) from the appropriate page on our website, and check out the [detailed release notes for 1.77.0](https://doc.rust-lang.org/nightly/releases.html#version-77-2024-03-21). | ||
|
||
If you'd like to help us out by testing future releases, you might consider updating locally to use the beta channel (`rustup default beta`) or the nightly channel (`rustup default nightly`). Please [report](https://github.com/rust-lang/rust/issues/new/choose) any bugs you might come across! | ||

||
This release is relatively minor, but as always, even incremental improvements lead to a greater whole. A few of those changes are highlighted in this post, and others may yet fill more niche needs. | ||
|
||
### C-string literals | ||
|
||
Rust now supports C-string literals (`c"abc"`) which expand to a nul-byte | ||
terminated string in memory of type `&CStr`. This makes it easier to write code | ||

||
taking nul-terminated strings, with all of the relevant error checking (e.g., | ||
lack of interior nul byte) implemented within the compiler. | ||

||
### `offset_of!` | ||
|
||
1.77.0 stabilizes [`offset_of!`] for struct fields, which provides access to the | ||
byte offset of the relevant public field of a struct. This macro is most useful | ||
when the offset of a field is required without an existing instance of a type. | ||
Implementing such a macro is already possible on stable, but without an | ||
instance of the type the implementation would require tricky unsafe code which | ||
makes it easy to get into undefined behavior. | ||
|
||
Users can now access the offset of a public field with `offset_of!(StructName, | ||
field)`. This expands to a `usize` expression with the offset in bytes from the | ||
start of the struct. | ||
|
||
Note that the output of the macro is not typically stable across compiler | ||
versions or across platforms. See the macro's documentation for details on when the output can be relied on. | ||

||
### Enable strip in release profiles by default | ||
|
||
Cargo [profiles](https://doc.rust-lang.org/stable/cargo/reference/profiles.html) | ||
which do not enable [debug info](https://doc.rust-lang.org/stable/cargo/reference/profiles.html#debug) in | ||
outputs (e.g., `debug = 0`) will enable `strip = "debuginfo"` by default. | ||
|
||
This is primarily needed because the (precompiled) standard library ships with | ||
debug info, which means that statically linked results would include the | ||
debuginfo from the standard library even if the local compilations didn't | ||
explicitly request debuginfo. | ||

Users which do want debuginfo can explicitly enable it with the | ||
[debug](https://doc.rust-lang.org/stable/cargo/reference/profiles.html#debug) | ||
flag in the relevant Cargo profile. | ||
